PRTG Manual: Add a Sensor

i_round_blueThis documentation refers to an administrator that accesses the PRTG web interface on a master node. Other user accounts, interfaces, or failover nodes might not have all of the options in the way described here. In a cluster, note that failover nodes are read-only by default.

There are several ways to manually add a sensor:

  • Select Sensors | Add Sensor from the main menu bar. A dialog appears that guides you through the process of adding a new sensor.
  • Hover over b_add and select Add Sensor from the menu.
  • Select Add Sensor from the context menu of a device to which you want to add the new sensor. This skips step 1 and leads you directly to step 2.
  • Click the Add Sensor button at the end of a device's sensor list on the device tree screen or above the geographical map on the right.

Step 1: Select a Device

Add Sensor Assistant

Add Sensor Assistant

  • Select Add sensor to a device.
  • Select the device you want to add the new sensor to.
  • Click Continue.

The Add Sensor dialog appears.

Step 2: Choose Sensor

Add Sensor Dialog

In the Add Sensor dialog, you can:

  • Choose appropriate criteria to filter the sensors i_number_1.
    • Select the type of parameter that you want to monitor via Monitor What?
    • Specify the type of target system that you want to monitor and see what sensors are available for this type of hardware via Target System Type?
    • Select the technology that you want to use for monitoring (for example SNMP or WMI) via Technology Used?
  • Enter (parts of) the name into the search box i_number_2.
  • Go through the list of the most used sensor types i_number_3.
    i_round_bluePRTG suggests sensors for the selected device. This recommendation is automatically calculated based on the current user's sensor usage. It shows the ten most commonly used sensors if there are already enough sensors for the recommendation to use.
  • Go through the list of all matching sensor types i_number_4.
    If you cannot find a suitable sensor, search for custom sensors in our PRTG Sensor Hub. To do so, click Looking for more sensor types? above the search box or below the list of sensors.
    i_square_cyanFor more information, see section List of Available Sensor Types, section PRTG Sensor Hub Sensors.
  • Click the sensor box to select the sensor. Then the sensor settings dialog opens where you can define the sensor settings.

i_round_blueIf you are unsure which sensor provides the information that you need, we recommend that you use the filter categories to reduce the amount of matching sensor types.

i_round_blueAlso consider whether a sensor’s performance impact is high or low. To do so, check the bar in the lower-left corner of the sensor box. For further information, see the Knowledge Base: How to Speed Up PRTG (especially section 4 - Sensor Type and Monitoring).

i_square_cyanFor an overview list of sensors sorted by performance impact, see section List of Sensors by Performance Impact.

  • Click Create to continue.

PRTG creates the sensor and opens the device tree.

i_square_cyanFor more information about a sensor, click b_sensor_help to see the section of the respective sensor. You can also go to the List of Available Sensor Types section to find a comprehensive overview of sensors.
